The C-76 Classic Water Bath Shaker is a shaker utilizing an eccentric counterbalanced drive to
provide horizontal plane rotary motion in a 1/2” (1.3 cm) circular orbit. A Proportional/Integral
(PI) Microprocessor controller with instantaneous digital feedback controls the speed over a
range of 50-300 RPM. It also provides temperature control over a range of 7°C above ambient to
80°C. For lower temperatures, an optional water bath cooling coil is available.
The shaker may be operated either continuously or in a timed mode via a programmable timer for
shaking periods of 0.1 hour to 99.9 hours.
In addition, the C-76 is equipped with visual alarms that alert the user to the following
conditions:
• The end of a timed run
• Deviations in shaking speed
• Deviations in temperature
• Power failure
A wide variety of platforms can be used with the C-76. Dedicated platforms are available for a
variety of flask sizes. Universal platforms, utility trays, utility carriers and test tube racks are
also available.

3.1 Physical Location
It is essential that the instrument be situated in an area where there is sufficient space
for the shaker and platform to clear walls and potential obstructions during operation.
The surface on which the unit is placed must be smooth, level, and able to support the
shaker under full load operating conditions.
3.2 Environment
The shaker is designed to operate optimally in the following ambient conditions:
• 5 - 35°C
• 20 to 90% Relative Humidity, non-condensing

3.3 Drain Valve Connection
The unit should be placed in close proximity to an open drain.
It is recommended that a 3/8” ID hose be connected to the DRAIN VALVE for draining
the bath. The DRAIN VALVE is located near the rear of the unit, on the side opposite
the ON/OFF SWITCH (see Figure 1 below).

3.4 Cooling Coil Connections
If your water bath is equipped with an optional COOLING COIL, prepare the coil for
operation:
1. Remove the rear panel of the WATER BATH ASSEMBLY from the unit (see Figure
2).

GROMMETS

2. Knock out the two plugs on the center of the two grommets on the rear panel (see
Figure 3).

3. Slip two lengths of 3/8 inch (9.5 mm) ID hose with hose clamps over the coil
ends. The hoses should be long enough to suit water or coolant supply and return
(drain) length requirements. Be careful to note or label the operation of each
hose.
4. Allow 1/8 inch (3 mm) to 3/16 inch (5 mm) of hose to extend beyond the hose
clamps and secure in place. Ensure that the clamps do not damage the hose.
5. Feed the two lengths of hose through the grommets on the rear panel and reattach
the rear panel to the unit.
6. Connect and secure the two remaining hose ends to their appropriate connections.
One line must go to an open drain or return to a coolant supply, and the other line
must be adapted to a water or water supply. If tap water will be used as a coolant,
the supply hose should be attached to a control valve to minimize water use.
